Prefabricated and Modular Construction

Detailed overview of innovation with sample startups and prominent university research


What it is

Prefabrication and modular construction involve the off-site manufacturing of building components or entire modules, which are then transported to the construction site for assembly. This approach contrasts with traditional construction, where most of the work is done on-site. Prefabrication typically involves manufacturing individual components like walls, floors, and roof trusses, while modular construction goes further by assembling complete rooms or units off-site.

Impact on climate action

Prefabrication and modular construction revolutionize low-carbon building materials by streamlining production, reducing waste, and enhancing energy efficiency. This innovation significantly lowers construction-related emissions, expediting climate action by promoting sustainable infrastructure development worldwide. It’s a pivotal step toward achieving carbon neutrality in the construction sector, combating climate change.
